Kev tsim cov txheej txheem ntawm aluminium alloy couplings yog ib qho kev taug kev uas hloov cov khoom siv raw mus rau hauv siab -cov khoom siv tshuab precision. Tsis zoo li cov ntaub ntawv ib txwm muaj xws li hlau lossis tooj dag, txhuas xav tau cov txheej txheem tshwj xeeb kom ua tiav cov qauv tsim nyog, kev ua haujlwm zoo, thiab kev coj tus cwj pwm zoo rau kev thov siv xws li pneumatic, hydraulic, thiab kev tswj lub zog. Cov hauv qab no qhia txog lub hauv paus txoj hauv kev hauv kev tsim khoom no.
Kub nias thiab kho cua sov
Txoj kev tsim kho tshaj plaws rau kev ua tau zoo -kev ua tau zoo aluminium alloy couplings yog kub nias, txheej txheem uas kov yeej cov kev txwv ntawm tus qauv siab tuag-casting, uas feem ntau ua rau cov khoom tawg thiab tsis muaj qhov sib xws. Txoj kev no pib nrog preheating aluminium alloy bars nyob rau hauv lub cub tawg mus rau ib tug sib xws kub, feem ntau ntawm 430℃thiab 470 degree, npaj cov khoom rau deformation. Tom qab ntawd lub preheated bar yog muab tso rau hauv ib tug forging tuag thiab nias los ua tus ntxhib zoo ntawm lub coupling.
Tom qab kev ua haujlwm nias, cov khoom siv tau ua tiav qhov tseem ceeb ntawm kev kho cua sov kom ua tiav nws cov khoom siv kho tshuab kawg. Kev solubilization lossis kev daws teeb meem kev kho mob yog ua los ntawm reheating qhov chaw rau qhov kub ntawm 515℃thiab 525℃rau tsawg kawg yog ob teev. Cov txheej txheem no tso cai rau cov ntsiab lus alloying kom yaj uniformly rau hauv aluminium matrix. Tam sim ntawd tom qab, tsis pub dhau 30 vib nas this, cov khoom tau txais kev kho thermal hardening- nrawm nrawm hauv chav da dej hauv qab 40℃- uas kaw cov ntsiab lus nyob rau hauv qhov chaw, tsim kom muaj cov tshuaj supersaturated. Tom qab lub sijhawm luv luv ntawm ob mus rau peb teev, cov khoom yuav raug rau cov laus laus hauv lub cub tawg ntawm 135℃txog 145℃rau kwv yees li yim teev. Cov kauj ruam kev laus no precipitates cov alloying ntsiab, ho nce hardness thiab lub zog ntawm aluminium coupling. Cov kauj ruam kawg feem ntau suav nrog kev kho anodic oxidation, uas tsim ib txheej nyias, tiv thaiv ceramic rau saum npoo, txhim kho corrosion thiab hnav cov khoom.
Advanced Forming Technologies
Rau cov tswv cuab ntawm cov txheej txheem nyuaj, tshwj xeeb tshaj yog loj - nplai los yog intricately cov ncauj lus kom ntxaws aluminium alloy couplings, advanced forming technologies yog ua hauj lwm. Ib qho kev tsim kho tshiab no yog qhov txias -kub sib txuas ua ke ua txheej txheem. Txoj kev no ua ke ob txoj kev sib txawv hauv ib qho kev teeb tsa tuag. Thaum pib, daim ntawv txhuas yog tsim los siv cov kua dej - puv chamber los tsim cov yam ntxwv tseem ceeb ntawm ntu. Tom qab ntawd, rhuab movable inserts nyob rau hauv tib neeg tuag ua ib tug kub stamping lag luam los tsim localized, complex cov ntsiab lus zoo li me me radii los yog dimples uas yuav nyuaj rau ua tiav nrog ib tug txheej txheem. Txoj kev ua ntu zus no ua kom muaj kev ncaj ncees ntawm tag nrho cov duab thaum tso cai rau kev tsim cov yam ntxwv zoo yam tsis muaj cov cuab yeej siv los ua kom muaj zog lossis ua kom muaj txiaj ntsig ntau lawm.
Lwm txoj kev koom nrog thiab tsim cov txheej txheem
Tshaj li kev sib sau monolithic, aluminium alloy couplings kuj tseem tuaj yeem tsim los ntawm kev sib koom ua ke siab heev uas siv cov khoom siv sib cuam tshuam thiab kev sib txuas ntawm metallurgical. Kev sib txhuam do tsim thiab kev sib txhuam do vuam yog cov khoom siv- lub xeev cov txheej txheem uas siv cov cuab yeej tig los ua kom muaj kev sib txhuam kub thiab cov yas deformation. Qhov ntsuas kub no-txheej txheem kev ua haujlwm tso cai rau kev sib koom ua ke ntawm aluminium alloys rau lawv tus kheej lossis cov khoom sib txawv xws li tooj liab yam tsis tau ncav cuag lub melting point, yog li zam kev tsim cov nkig intermetallic compounds uas tuaj yeem ua rau muaj kev sib koom ua ke. Ib qho kev sib txawv, kev sib txhuam do riveting, ua ke ua ntej -drilled qhov nrog lub txee- khoom los tsim kom muaj kev sib txuas ntawm cov khoom siv sib txuas nrog atomic diffusion ntawm lub interface, ua rau muaj kev sib txuas siab -. Lwm txoj kev tawm tshiab yog siv cov txheej txheem electrochemical etching los tsim micro- nplai nuv cov qauv ntawm aluminium nto, ua kom muaj zog mechanical interlocking nrog adhesives los yog txawm nrog lwm cov ntaub ntawv nyob rau hauv chav tsev kub, nthuav qhia ntau yam kev xaiv rau cov tsoos vuam.
Hauv kev xaus, kev tsim kev taug kev ntawm aluminium alloy coupling yog txhais los ntawm kev xaiv ntawm cov txheej txheem tshwj xeeb. Txawm hais tias los ntawm cov txheej txheem thermal zoo ntawm kev kub nias thiab kev kho cua sov, kev sib xyaw ua ke ntawm txias -kub sib txuas ua ke, lossis cov khoom tsim tshiab- xeev cov txheej txheem ntawm kev sib txhuam do technologies, txhua txoj hauv kev yog tsim los qhib lub peev xwm ntawm txhuas, tsim cov khoom sib sib zog nqus, muaj zog, thiab txhim khu kev qha rau kev siv tshuab tseem ceeb.
